YNGTB series dry-type test transformers use excellent production equipment, adopt the new technology of coil winding epoxy vacuum casting and CD-type iron core. Compared with similar products of oil-immersed transformers, it significantly reduces the weight, volume, and quality. Improve the insulation strength and moisture resistance, and effectively weaken the magnetic leakage and greatly strengthen the transformer's ability to withstand the impact of the test short-circuit current.

YNGTB series dry-type test transformers have the characteristics of light weight, small size, beautiful appearance, stable performance, easy to use and carry, etc., especially suitable for on-site operation and use. It is a new generation of new AC and DC dual-purpose high voltage test transformers in China. This series of generators is suitable for power systems and various power users to detect the insulation performance test of various electrical equipment on-site, and the high-voltage power supply in various voltage systems or devices of DC high-voltage and low-current electrical products.
